Well you can fantasize of course :-) Actual small flyers with both useful range and telemetry are still science fiction. The number to watch is the energy density / energy consumption ratio. Dragonfly like devices can currently get airborne and fly a few 10s of meters, but that is without any cargo capacity at all.

Not that someday it won't happen, rather that today you could carry a 12 ga shotgun shell around with a camera that lets you see where you are. All of that tech is 'off the shelf' today. Hence the more immediacy of the change.
